This invention relates to a mechanism and system for interchangeable furniture bases with interlocking connections. More particularly, this invention relates to a mechanism and system for quickly and easily interchanging various furniture bases with various furniture seats or seat boxes by means of an interlocking connection, such as a multi-part cam assembly.
Ready to assemble furniture is very popular because it can be easier to assemble and relatively inexpensive as compared to fully assembled furniture. However, there are pieces of furniture that have been proven to be exceedingly difficult to provide as ready to assemble furniture.
Reclining furniture with rocker, glider, swivel and other mechanisms create particular problems when used in ready to assemble furniture. In fact the precision of preparing the interlocking parts is typically beyond the ability of the average person working with ready to assemble furniture. The present invention addresses this deficiency and provides a system for quickly and easily interchanging various furniture bases with various furniture seats or seat boxes by means of an interlocking connection, such as a multi-part cam assembly. The multi-piece cam further provides a configuration that is more easily disassembled and serviced in the field.
In various embodiments, the present invention comprises a system for quickly and easily interchanging various furniture bases with various furniture seats or seat boxes by means of an interlocking connection, such as a multi-part cam assembly. A furniture base can be quickly and easily detached from a particular seat box, and replaced by a different style of furniture base.
The present invention further comprises a mechanism for assembling and connecting a furniture base to a piece of furniture. The assembly comprises a furniture base having a first cam piece, configured with a first cam interlock, associated therewith; a furniture frame having a second cam piece, configured with a second cam interlock, associated therewith; with each of said first cam and second cam interlocks configured to mate and interlock one to another to form a cam. In an alternative configuration, the first cam piece and second cam piece are a first connector piece and a second connector piece, with interlocks configured to mate and interlock one to another to form a connector.
The mechanism, whether in cam or connector form, is configured to be used with a multitude of furniture bases and seats or seat boxes, including, but not limited to recliner mechanism bases, rockers, gliders, swivels, swivel rockers, swivel gliders, twin sleepers, full sleepers, queen sleepers, king sleepers, or combinations thereof.
In one embodiment, the first cam piece is a system including two or more cam units or sub-pieces. In another embodiment, the second cam piece is a system including two or more cam units or sub-pieces. The first cam piece may have two or more first cam interlocks, and the second cam piece may have two or more second cam interlocks.
In one exemplary embodiment, the first cam interlock is integrated onto said first cam piece. Similarly, the second cam interlock may be integrated onto said second cam piece. In several embodiments, the first cam interlock and said first cam piece are constructed of a unitary piece. The second cam interlock and said second cam piece also may be constructed of a unitary piece. The first cam interlock and said second cam interlock connect in a snap-fit locking arrangement.
The present invention further contemplates a method of connecting a furniture base to furniture, said method comprising the steps of: providing a first cam piece and second cam piece according to any of the configurations or combinations disclosed herein; associating said first cam piece with a furniture base; connecting said second cam piece to either a furniture seat box or a reclining mechanism; positioning said first and second cam pieces to align respective interlocks; and interlocking each of said first and second cam pieces one to another.
In various embodiments, the present invention comprises a system for quickly and easily interchanging various furniture bases with various furniture seats or seat boxes by means of an interlocking connection, such as a multi-part cam assembly. A furniture base can be quickly and easily detached from a particular seat box, and replaced by a different style of furniture base. The present system suitable for all furniture, reclining or non-reclining, where connection is desired, such as, but not limited to, sofas, loveseats, chairs, sectional pieces, ottomans, rockers, gliders, swivels, swivel rocker, sleepers, and the like, each with their respective seat boxes and bases. The present invention allows the furniture seat boxes and bases to be disconnected and connected in various combinations as desired, by the consumer, the retail store, or others, as described above.
In several embodiments, the present invention enables a glider base (in various forms) to be attached to a rocker scissor mechanism attached to a seat box or seat. This avoids the requirement for a glider side assembly mechanism to be separately attached to the scissor mechanism, as is the case with prior art rocker gliders. The present invention thus allows a rocker to be converted to a rocker-glider or a glider without the need of a separate glider side assembly mechanism, thereby reducing parts and costs.
In several further embodiments, two or more cross tubes extend laterally between the two sides of the bases (in the embodiments shown, the cross tubes extend between the right and left lower pieces of the cam assembly). The cross tubes may be bent or curved, as shown. This allows the cross tubes to pack efficiently around the drive tube, when the base is packed with a seat box, seat or upper furniture component.
The present invention further comprises a multi-piece cam assembly for furniture. The figures are demonstrative and the invention contemplates multiple configurations including, but not limited to two, three, four, and five cam component systems.
As generally understood, ready to assemble furniture is constructed such that an ordinarily skilled consumer can assemble the furniture. Reclining mechanisms are typically exceedingly complex and furthermore locking mechanisms are often excluded from ready to assemble furniture products.
In one embodiment, the two-piece cam is suitable for assembling a furniture base to the seat box portion of furniture. It is further contemplated that the present invention is suitable for connection of reclining mechanisms to a base in ready to assemble furniture. Reclining furniture is without limitation and includes, but is not limited to, a rocker, glider, swivel, swivel rocker, swivel glider, power variations of all of the above, sleepers, or any piece of furniture that utilizes reclining mechanism. However, the multi-piece cam assembly is suitable for all furniture, reclining or non-reclining, where connection is desired, such as, but not limited to, sofas, loveseats, chairs, sectional pieces, ottomans, rockers, gliders, swivels, swivel rocker, sleepers, and the like, each with their respective seat boxes and bases. The present invention allows the seat boxes and bases to be disconnected and connected in various combinations as desired, by the consumer, the retail store, or others, as described above.
In one embodiment, the two-piece cam is particularly well suited for connecting a furniture frame to a base. Although the drawings demonstrate a first cam piece as a locking cam connected to a furniture frame and a second or receiving cam piece connected to a base, the locking/receiving configurations are interchangeable.
First cam piece, configured as a receiving cam 20 is constructed and arranged with a locking orifice 24. Orifice 24 is constructed and arranged to interact with locking tab 34 on locking cam piece 32.
Receiving cam piece 20 has formed thereon a horizontal support receiver 22 which is constructed and arranged to receive horizontal supports 36 of the present invention. In one embodiment, as seen in
The locking cam piece 32 of the present invention is constructed and arranged to affix to the seat box or scissor/main assembly of a reclining mechanism of a piece of furniture. In one embodiment, locking cam piece 32 is affixed to the seat box. In another embodiment, the seat box frame or recliner frame is formed with a cam portion integral therewith. Since locking cam piece 32 is affixed to the underside of an article of furniture it is positioned above receiving cam piece 20 whereby locking tab 34 interacts with locking tab 24 in order to removably interconnect locking cam piece 32 with receiving cam piece 20.
Either or both of the cam pieces can in turn be provided in two or more separate sub-pieces. For example, in the embodiment of
In use, receiving cam piece 20 is positioned over a prepared upper surface 28 of furniture base 30. When locking cam piece 32 is positioned and locked onto receiving cam piece 20 the article of furniture attached thereto will be able to rock along base 30. Base 30 is constructed and arranged to have two main base portions each being 30 that are interconnected by transverse supports 38. Cam piece 20 has receiving socket 42 configured to mate with positioning tab 40 of locking cam piece 32.
In one embodiment the invention is a mechanism for a piece of furniture comprising: two or more locking cam pieces, constructed and arranged with at least one locking mechanism on each cam piece; two or more receiving cam pieces, said receiving cam pieces are constructed and arranged to receive said locking mechanism, said interconnected cam pieces are configured to be used in reclining furniture and sleepers to include, but not limited to, rockers, gliders, swivels, swivel rockers, swivel gliders, twin sleepers, full sleepers, queen sleepers, king sleepers. In addition, this mechanism assembly covers power reclining variations.
Although a particular embodiment is demonstrated, the multi-piece cam is contemplated to connect and disconnect in a male-female interlock arrangement. The two-piece cam represents a significant and unforeseen improvement in furniture design and construction by providing a construction element that improves ease of assembly and disassembly. The multi-piece cam assembly is suitable not only for rocking, reclining, and gliding assemblies, but for all furniture in which there is the attachment of a mechanism to a frame base. The multi cam configurations provide additional benefit relating to simplification of the assembly process.
An end interlock mechanism comprises one or more end tabs 140a, b extending from the end or ends of a cam piece, and a corresponding slot or groove 142 a, b, with or without walls or tabs of its own, on the inside of the end or ends of the other cam piece, the slot or groove 142a, b adapted to receive the corresponding one or more end tabs 140a, b. A locking tab or tabs 150 in the end interlock mechanism on one cam piece engages a corresponding hole, opening, slot, groove or tab 152 in the end interlock mechanism on the other cam piece to removably secure the one or more end tabs 140a, b within the corresponding slot or groove 142a, b. To separate the cam pieces, a tool or instrument, such as, but not limited to, a screw-driver, may be inserted into an opening in the end interlock mechanism to release the locking tab or tabs 150. In several embodiments, the end interlock mechanisms also serve as positioning elements in addition to locking or connection elements.
While
Similarly, one or more rectilinear elements or blocks, 170a, b, 180a, b, 190, may be positioned along a side of the receiving or locking cam (and may be positioned along or near the top of the particular cam element), with a corresponding receiving hole or slot, 172a, b, 182a, b, 192, located along or in a corresponding side of the other cam piece element. These elements may be of substantial size, and thus provide additional support and strength to the cam when assembled. For example, the sides of rectilinear elements 170a, b may comprise channels 174 adapted to receive corresponding tabs or ribs 176 along the inside of the corresponding receiving slot or hole, 172a, b. Further, one or more of these elements may incorporate or include one or more of the horizontal support receivers 22.
In several embodiments, a central positioning element 190, 192 is provided to provide additional strength and security for the assembled cam pieces. Positioning element 190 may be a simple block or flat extension, or may be L-shaped in cross-section, with a outermost element 194 that latches over or slides into a groove or slot 196 in the corresponding positioning element. This positioning element also may serve as an additional central interlock mechanism as described above, providing three or more interlock points in conjunction with the two
In several embodiments, one or more horizontal attachment tabs or elements 200a, b are located along or near the top of the upper cam piece 130, the horizontal attachment tabs or elements comprising bolt holes or slots 204 for attaching one or more mechanisms or furniture components to the cam. piece. The horizontal attachment tabs 200a, b also may comprise or be an extension of a positioning element, such as blocks 180a, b, as described above, and fit within corresponding grooves or channels 182a, b in the lower cam piece 120. In the embodiment shown in
As seen in several of the figures, when assembled or connected, sections of the top of the lower cam piece 120 are level with the top of the of the upper cam piece 130. Due to the nature and placement of the positioning elements, however, in several sections the top of the upper cam piece 130 extends over the corresponding top section of the lower cam piece 120. The connected cam assembly thus provides multi-axis strength and durability, with resistance to movement of the cam pieces with respect to each other after connection, which can lead to breakdown or failure of one or more of the cam pieces during use.
In this embodiment, there are no elements of either cam piece extending outward from the sides of either cam piece, individually or in a conjoined configuration (i.e., the sides are “flat”). Horizontal supports are inserted into one or more cavities, orifices or openings 322 in the side of a cam piece, and which may extend through some or all of the width of the cam piece. The configuration has the advantage of a simpler efficient design without exposing any extended elements to damage or breakage during shipping or assembly.
Fastening means, such as a hole 312a, b, on the interior of the orifice 322 may be used to receive a spring-based tab or extension element on the horizontal support to hold the horizontal support securely in place. The fastening means can be released by pushing the tab or extension down or inwards. In other embodiments, the horizontal support may comprise a hole extending therethrough proximate to the end, and configured to align with matching holes 310a, b extending vertically through the cam piece and opening into the corresponding orifices 322. A screw or bolt may then be inserted into the holes 310a, b and through the corresponding holes in the horizontal support when inserted into the orifice.
